Nickel (II) chloride(aq) + sodium hydroxide (aq) --> ?
Is this right:
Molecular equation: NiCl2(aq) + 2NaOH(aq) --> Ni(OH)2(s) + 2NaCl(aq)
Ionic equation: Ni 2+ & 2Cl- & 2Na+ & 2OH- --> Ni(OH)2(s) & 2Na+ 2Cl-

Sounds good.

I'll second that.

Equation:
NiCl2(aq) + 2NaOH(aq) ---> Ni(OH)2(s) + 2NaCl(aq)
Ionic:
Ni2+(aq) + 2Cl-(aq) + 2Na+(aq) + 2OH-(aq) ---> Ni(OH)2(s) + 2Na+(aq) + 2Cl-(aq)
Net ionic:
Ni2+(aq) + 2OH-(aq) ---> Ni(OH)2(s)
-
Ni2+(aq) + 2OH-(aq) ---> Ni(OH)2(s)
Should be
Ni2+(aq) + 2OH-(aq) ---> Ni(OH)2(s)
(note (aq) and (s) are not subscripts!).

(note (aq) and (s) are not subscripts!).
Can you please provide a reference for this :)

Fantastic! Thanks Borek :) :)
